We went out with Allah's Messenger (ﷺ) in the year of Al-Hudaibiya. One night it rained and Allah's Messenger (ﷺ) led us in the Fajr prayer and (after finishing it), turned to us and said, "Do you know what your Lord has said?" We replied, "Allah and His Apostle know it better." He said, "Allah said:-- "(Some of) My slaves got up believing in Me, And (some of them) disbelieving in Me. The one who said: We have been given Rain through Allah's Mercy and Allah's Blessing and Allah's Bounty, then he is a believer in Me, and is a disbeliever in the star. And whoever said: We have been given rain because of such and- such star, then he is a believer in the star, and is a disbeliever in Me."
